My aunt broke in half the music record I found while walking the dog

I was outside walking the dog when I saw a CD player lying around, it had rained so it probably wasn’t working, but I decided to go closer to see it better, when I realized, inside there was a music CD, it was a classical music CD by Mozart, I searched on the internet and realized that they were sold for 3 dollars, it wasn’t even expensive, but, I had never listened to music on a CD, so I decided to take it, when I got home, my aunt sees that I have it with me, she asks me where I found it and I tell her, she tells me that it’s trash and that I threw it away, I tell her that it’s in perfect condition but she insists that it’s trash and that I threw it away, to the point of almost getting hysterical, I tell her Ok and I go to the dumpster, but I put it on the side so that it doesn’t get scratched and I can take it out later, she tells me that in her house I don’t have to bring trash like that, and she tells me that if I live with her I have to respect that rule, everything would seem fair, even I understand it, but the way she tells me that … She said it, she wasn’t nice, she insulted me calling me a 1cm brain. Yes, I know, I’m not the smartest person, but there was no need to call me that, I got upset and told her that she was the one with the 1cm brain for not understanding that it was just a record, it wasn’t even for her, it was for me, and that it didn’t affect her at all, but she got even more angry, so she took out the trash, took the record and broke it in two. I know that it wasn’t even an expensive record, and that I found it thrown inside a player, even so, why go to such extremes? Just to emphasize her authority? I understand that it’s her house and I have to respect her rules, and that maybe I should have kept quiet or hidden the record and thus it would have been saved, that it was a record that can be found new on the internet for 3 dollars, and that the music inside it can be listened to for free on the internet, even so, I don’t find it fair.
